. The coroner in Las Vegas states the body of the man who released the deadliest mass shooting in contemporary U.S. history has been sent out to Stanford University for research study.

Clark County Coroner John Fudenberg stated Friday that an autopsy was completed on 64-year-old Stephen Craig Paddock, but a finding on a cause and way of his death is not anticipated for several months.

Fudenberg states it will await the outcomes of several forensic analyses at Stanford, including a neuropathological evaluation of Paddock’s brain tissue.

The coroner says the bodies of all 58 victims in the Oct. 1 shooting at the Path 91 Harvest Festival concert on the Las Vegas Strip were gone back to next-of-kin by Oct. 6.

Fudenberg says Paddock’s body will be gone back to his household after forensic test outcomes are known.
